It's understandable that medical products company Z-Medica Corp. proudly salutes the 4.5-mil film structure for its line of QuikClot blood-clotting products. After all, the pouch has accommodated several generations of product iterations, and is now targeted for both military operations and consumers such as sports and adventure enthusiasts who may venture far from medical attention. From Versapack , the pouches are shipped premade to Z-Medica three-side-sealed. The pouch is an adhesive lamination of polyester/foil/nylon/polypropylene. The polyester is reverse-printed in four to six colors, depending on the variety.
